A series of cyclic push-out tests on specimens with shear studs and steel deck with concrete fill is initiating in

Concrete-filled steel deck is employed as a diaphragm in countless structural steel buildings. However, the available experimental data on cyclic

The NSF-sponsored team focusing on seismic collectors in steel buildings, an effort highly compatible with the overall SDII initiative –

The performance of steel-to-steel connectors in shear are important for cold-formed steel deck diaphragms, but also for a variety of

Recent testing conducted by NBM Technologies provides cyclic characterization of both deck-to-deck sidelap and deck-to-frame structural connectors. The tests cover

Simulation of steel structures has advanced markedly in the finite element age and today models that include buckling and yielding

Using a simplified nonlinear mass-spring model this work provides an examination of how inelasticity in the vertical and horizontal (diaphragm)

A recent SDII conference paper provides additional insight on how bare steel deck diaphragms warp under shear. The paper provides

The National Science Foundation has recently funded a team lead by Robert Fleischman (Arizona), Chia-Ming Uang (UC-San Diego), James Ricles

SDII is pursuing advanced models of steel and steel-concrete systems. For many of these models the computational time is extreme,
